Instant Account Verification, Zero Friction

AI-powered verification emails deliver in seconds with time-limited tokens and security context. Never lose a signup to email delays again.


Why this matters

Delayed verification emails kill conversion rates during signup. Every second a user waits for their verification link is a chance they abandon the flow entirely. Manual processes and unreliable email infrastructure create friction at the most critical moment in the customer journey.


How MultiMail solves this

MultiMail's autonomous mode sends verification emails instantly when signup events fire. The AI composes security-aware messages with time-limited tokens, IP context, and clear calls to action. Autonomous delivery is safe here because verification emails are templated and time-critical.

1

Receive Signup Event

Your application triggers a verification request when a user signs up or changes their email address. MultiMail's API receives the event and begins composing the verification email immediately.

2

Generate Secure Token

Your backend generates a time-limited verification token. The AI composes an email with the token link, expiration time, and security context like the requester's IP address and browser.

3

Send Immediately

In autonomous mode, the verification email is sent without delay. No approval queue, no human bottleneck — just instant delivery of a security-critical message.

4

Track Delivery and Opens

MultiMail logs delivery status and engagement. If the verification email bounces, your application can prompt the user to re-enter their address or try an alternative verification method.


Implementation

Send Verification Email on Signup
python
import requests
import secrets
from datetime import datetime, timedelta

API = "https://api.multimail.dev/v1"
HEADERS = {"Authorization": "Bearer mm_live_xxx"}

def send_verification(user_email: str, user_name: str):
    token = secrets.token_urlsafe(32)
    expires = datetime.utcnow() + timedelta(hours=24)
    verify_url = f"https://app.example.com/verify?token={token}"

    response = requests.post(
        f"{API}/send",
        headers=HEADERS,
        json={
            "from": "[email protected]",
            "to": user_email,
            "subject": "Verify your email address to get started",
            "text_body": f"Hi {user_name}, click here to verify: {verify_url}\nThis link expires in 24 hours.",
            "html_body": f"<p>Hi {user_name},</p><p><a href=&"cm">#039;{verify_url}'>Verify your email</a></p><p>This link expires in 24 hours.</p>"
        }
    )
    return response.json()

Trigger an instant verification email when a new user registers, including a time-limited token link.

Handle Email Change Verification
python
import requests

API = "https://api.multimail.dev/v1"
HEADERS = {"Authorization": "Bearer mm_live_xxx"}

def verify_email_change(new_email: str, user_name: str, ip: str):
    verify_url = generate_verification_url(new_email)

    response = requests.post(
        f"{API}/send",
        headers=HEADERS,
        json={
            "from": "[email protected]",
            "to": new_email,
            "subject": "Verify your new email address",
            "text_body": (
                f"Hi {user_name}, an email change was requested "
                f"from IP {ip}. Verify: {verify_url}\n"
                f"If you didn&"cm">#039;t request this, ignore this email."
            )
        }
    )
    print(f"Verification sent: {response.json()[&"cm">#039;id']}")

Send a verification email when an existing user updates their email address, with security context.

MCP Tool Integration
typescript
"cm">// Send verification email via MCP tools

const verifyUrl = generateVerificationUrl(userEmail);

await mcp.send_email({
  from: "[email protected]",
  to: userEmail,
  subject: "Verify your email address to get started",
  text_body: `Hi ${userName}, click the link below to verify your email address. This link expires in 24 hours.\n\n${verifyUrl}`,
  html_body: `<p>Hi ${userName},</p><p><a href="${verifyUrl}">Verify your email</a></p><p>Link expires in 24 hours.</p>`
});

"cm">// Add to contacts once verified
await mcp.add_contact({
  email: userEmail,
  name: userName,
  tags: ["verified", "new-signup"]
});

Use MultiMail MCP tools to send verification emails directly from your AI agent.

autonomous
Verification emails are templated, security-critical, and time-sensitive. Any delay from human review would degrade the signup experience. Autonomous mode ensures instant delivery for these low-risk, high-urgency messages.

Common questions

Why is autonomous mode safe for verification emails?
Verification emails are templated with dynamic tokens — there's no AI-generated content that could go wrong. The message format is predictable and the only variable is the token URL. Delaying these emails with human review would hurt conversion rates without adding safety.
How quickly are verification emails delivered?
MultiMail sends verification emails within seconds of receiving the API call. Autonomous mode has no approval queue, so the only latency is network transit and mail server processing. Most users receive their verification email in under 30 seconds.
What if the verification email bounces?
MultiMail tracks delivery status for every email. Your application can poll the email status endpoint or configure webhooks to detect bounces immediately, then prompt the user to re-enter their email address or try an alternative verification method.
Does this support email change verification too?
Yes. The same flow works for email address changes on existing accounts. Include the requester's IP and timestamp in the email body so the account owner can identify unauthorized change attempts.
